Fully understand why you feel the way you do, especially as it's come out of the blue. I don't know if low BMI is a factor, although I think 19/20 is in the healthy range anyway. Have you tried doing the calculation yourself to see what score you are? Take care of yourself.I’ve just received an email and I’m pretty shocked and upset if I’m honest. I just can’t work out why! I have gastroparesis, would that be enough? My BMI is low, 19 or 20 I think, is low BMI a factor or is it just higher? I’m a carer on a low income, but our postcode is generally ok
